What Does Uptake On Pet Scan Being Same As Blood Vessel Mean
No: SUV has no bearing on the aggressiveness of the cancer. It is a relative measure of the glucose metabolism. In fact, some very aggressive tumors have no FDG uptake at all. Some benign conditions like infection can have high uptake. The standard uptake value depends on many factors like patient body size and serum glucose level and the normal uptake in the tissue surrounding the target lesion. ...Read more
Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more
PET scan said for sarcoidosis: On FDG images, there is diffuse FDG uptake throughout the left ventricle wall including the septum. What does that mean?
Ask your doc...: FDG-enhanced PET/CT is to show the unusual increase or decrease in glucose metabolism at certain areas of the body especially inside a mass - before or after drug treatment. Based on the features and distribution of FDG imaging enhancement as defined from experience, a diagnosis can be drawn; of course, biopsy is ultimate means for confirmation. So, ask doc - treating or radiologist timely. ...Read more
PET scan said:
On FDG images, there is diffuse FDG uptake throughout the left ventricle wall including the septum.
What does that mean?
Need more informatio: You need to give us your medical history and explain the reason for doing a PET scan? Did you have chest pain or suspicion of heart disease?. What did your doctor tell you about the meaning of your PET scan report? FDG uptake is normal for the heart....lack of it might indicate a scar or damage to the heart muscle...but you do not seem to have that problem. ...Read more
Please can you explain what this means: Pet scan showed right lower lobe lesion with increased uptake SUVMAX20. Measuring 5x5cm &the right cervical ad?
PET Scan...: This PET scan is saying there is a lesion measuring 5x5 centimeters that is active physiologically-that is, it is using the isotope given during the scan. The lesion is located in the right lung, near the bottom. There are also some enlarged lymph nodes. This needs to be followed up closely because, although it may be benign, malignancy needs to be ruled out. A biopsy is likely the next step. ...Read more
What can this mean... Indeterminate uptake in the medistinial/ hilar nodes in a colon cancer pt ? This was noted from a pet scan . Can it mean mets ?
Indeterminate: Metastatic cancer causes increased metabolic activity in lymph nodes. Inflammation and othe conditions can also do that, but not as much. Indeterminate uptake means that the uptake is more than normal, but not so high as to make cancer virtually certain. The uptake is in the range where it could be cancer, but is more likely non-cancer. Hence, indeterminate. ...Read more
My nurse practioner says the valve that let's blood flow to my body is letting my blood flow too much.She is reading off a pet scan.What does this mean?I also have an anurism 4.8 .Could this cause tro
Mri reveled mass in ribs/thoracic. Dr ordered pet scan and blood work. Why not biopsy first? Does this mean cancer is definite?
Mass: Au contraire, your doctor is trying to save you from an invasive procedure and determine if the biopsy is necessary. The other tests are necessary before proceeeding, follow their advice. ...Read more
My husband has a melanoma on the right side of his stomach. Blood work, X-ray and pet scan are normal. Does that mean it is not nessery for a node biopsy?
Congenital: Variety of benign congenital brain vessel malformations, include venous angioma, small aneurysmal dilatations, arteriovenous malformations, even hemangiomas. But any of the above can cause great mischief under a variety of circumstances, so you need to discuss with your doctor what the findings truly mean for your future. ...Read more
A lesion was removed on my gum, it did not show on the c scan, I have to wait for the biopsy to find out if it a cyst or a blood vessel or what, Why?
examining tissue is the most accurate way to determine the type of lesion you have.
The specimen obtained needs to be processed and then examined under microscope. This takes time.
Be patient, take a deep breath, and lets hope for good news. ...Read more
My 2 yr old fell, hit her head. She quickly had a large bump that ran right along a blood vessel. It has gone down some with ice. What does this mean?
Falls and injuries: to the head often lead to a large bump because there is no soft tissue over the bone to absorb any blood from an injury.Children her age and younger often have prominent scalp blood vessels.If you are not seeing bleeding from that,I would not be concerned about that aspect.However, if she develops vomiting, sleepiness, different behavior than usual,or the bump enlarges a lot,see her doctor/ ER. ...Read more
Usually nothing: Sub conjunctival hemorrhage is a common condition. It may be due to blood pressure ore eye pressure. But usually a cause is not found. Any valsalva maneuver may cause a capillary to break, even heavy lifting or constipation. It is usually benign. But have your eyes checked. ...Read more
What are the chances of a lesion being serious if not seen on a c-scan. Can't a Dr. tell a cyst or blood vessel when he removes it.
Ask surgeon: I assume C scan is cat scan.Usually surgeon likes to know type of lesion dealing with. If it has large amount of blood vessels, cystic, or solid. Helps with surgical planning. Access to problem depends a lot on location I would want to know as much information preop as possible Some times soft tissue lesions are better seen with MR examination. You should have discussion with the physician ...Read more
Drs office called with chest xray results and said it showed a calcified blood vessel but dr wasnt worried. What does this mean? Should i worry?
Don't worry: Calcified blood vessel in the chest simply means that one of your blood vessels has some calcium in the lining. It is usually is not a problem especially at the age of 27. To be sure that there's nothing wrong you might ask what the results of your recent blood test were especially the metabolic panel ...Read more
I had a MRI done on my spine and brain. And it came back abnormal. I am asked to do a angiogram, wht could this mean. I have a cluster or blood vessel?
Answering why: Most doctors rule out or ensure the absence of life threatening events. A typical problem with a tumor that is cancerous is "angiogenesis" which is developement of new blood vessels. It does not mean that a cancer is there. It means that bads things are ensured to not be there. ...Read more
Is lips cut a mean of HIV transmission since it was tiny blood vessel not from the main vessel
If so will it delay the window period from this infect?
Cut lip issue: Any break in the protective barrier provided by skin or mucous membrane can act as a pathway for transmission of a blood-borne illness such as HIV. However, it is unlikely that the "window period" you mention would be delayed or lengthened by this location. The usually rule of thumb holds true--it can take up to 6 months for infection to appear. I would discuss this with your primary physician. ...Read more
Taking insulin pills now, woke up one morning with a popped blood vessel in my eye and a bruise next to belly button... What could this mean?
Uptake on PET: The uptake of 18F-FDG by tissues is a marker for the tissue uptake of glucose, which in turn is closely correlated with certain types of tissue metabolism. Tumors in general are more metabolically active than normal tissues and this difference in uptake is what makes PET scans possible. Tumors that have a higher metabolic rate will have more FDG uptake. Tumors that are less active havel less . ...Read more
A new findin of a liver lesion with 2.8 SUV uptake on pet scan in a colon can patient . Would this b a killed met?
So Why the test.: Tissues that are demonstrating a higher degree of metabolic activity will typically cause a greater degree of uptake to that tissue. In some situations, this uptake has a high degree of specificity and in others, it may not be so reliable. Your query would better be answered with more clinical information. ...Read more
Std Uptake Value: or SUV is a measure of the tumor's metabolic activity. The higher the SUV the more metabolically active the tumor. Metabolic activity often equates with rate of cell division and growth. An SUV of 5.2 is quite high. Values above 2.5 generally are highly suggestive of malignancy. Thanks for trusting HealthTap! ...Read more
9mm lung nodule found lower lobe on abdomininal scan. Follow up scan 6 months later nodule grew to 1.5 cm. PET scan no uptake former smoker 15 yrs ago?
What could be the causes of increased uptake by a nonenlarged subcarinal node on pet scan in a patient with breast cancer?
I had a pet scan in the brain . Doctor say my glucose uptake is low. How reliable are theses scans anyway?
Why the test?: The pet scan is used to evaluate tissues that are high metabolizers of glucose(sugar) like the brain the liver and tumors. Yhe tracer used is a radiolabeled glucose molucule which is picked up avidly by the tissues mentioned. Having low intake is of little value depending on the intent of the test ( what were they looking for? ...Read more

What does a pet scan for leukemia show? Since leukemia is in the blood, does it show cancer cells spread all over your body or does it show the cells concentrated in certain areas?
A PET scan: Would be utilized to show involvement of the lymph nodes which does occur in many leukemias. ...Read more
All the tests I took days everything's normal i know I have anxiety but my body doesn't feel normal. Dry mouth coughed blood. Hard beat isn't strong even when I workout it beats fast but not strong. Doing a nuclear stress should i get a pet scan?
Getting tests for no particular symptoms is not only wasteful of your money but can lead to unneeded treatments including surgery.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more
